Final answer:
Solids have a definite shape and volume.
Step-by-step explanation:
Solids have a definite shape and volume. Unlike liquids and gases, which can change their shape and volume based on the container, solids maintain their shape and volume regardless of the container they are in. For example, a cube of ice will maintain its shape and volume even if it is put in a different container. Therefore, the correct description for solids is solids have a definite shape and volume.
